Definitions

  • the present invention relates to a clamping assembly for an injection moulding apparatus.
  • Injection moulding apparatus typically comprises fixed and movable load-bearing platens which are adapted to clamp between them respective halves of a two-part mould.
  • pressure is applied to the movable platen so as to clamp together the two halves of the mould into which molten plastics material is then injected at pressure which can often be very high.
  • a high clamping force has to be applied so as to hold together the two sections of the mould.
  • a clamping assembly for an injection moulding installation comprising: rigid, elongated positioning and clamping structures with one of said structures substantially embracing the other; a fixed platen rigidly coupled to said positioning structure and articulatedly coupled to a first end portion of said clamping structure; longitudinal, axially directed sliding bearings formed integrally with said positioning member; a movable platen slidably supported on said bearings for free, axially directed displacement with respect to said positioning structure towards and away from said fixed platen; and platen drive means articulatedly coupled to a second and opposite end of the clamping structure and to the movable platen for imparting said displacement to said movable platen.
  • the apparatus is characterized by it being divided into two separate structures, namely the positioning structure and the clamping structure.
  • the assembly frame will be more rigid than existing frames, rendering installation in the customer's premises easier and simpler.
  • the proposed assembly is less sensitive than existing machines to the nature of the base surface on which it is to be mounted.
  • a clamping assembly for an injection moulding installation comprises a rigid, elongated, rectangular base frame 1 constituting a positioning structure having, at one end thereof, a pair of upwardly extending support posts 2.
  • An elongated, substantially rectangular clamping structure 3 nests within the base frame 1 and comprises an elongated planar base portion 4 and, at either end thereof, pairs of bearing posts 5 and 6.
  • the end of the clamping structure 3 adjacent the support posts 5 is formed with a pair of laterally extending support pins 7 which extend through a pair of longitudinally extending slots 8 formed in the base frame 1 so that the structure 3 is supported on the base frame 1 and is capable of limited longitudinal displacement with respect thereto.
  • a fixed platen 9 is formed integrally with the support posts 2 and with a rearwardly extending lug 10. The latter is located between the support posts 6 and is pivotally mounted with respect thereto by means of an axle 11.
  • a movable platen 14 is formed with a pair of rearwardly extending struts 15, the under edges of which rest on elongated ribs 16 integral with an upper edge of the base frame 1. These under edges of the struts 15, together with the ribs 16, constitute sliding contact bearings.
  • a hydraulic drive piston 21 is pivotally mounted between the posts 5 and has extending therefrom a piston drive rod 22 which terminates in a head portion 23 which is pivotally mounted to and between a pair of rearwardly extending lugs 24 formed integrally with a rear surface of the movable platen 14.
  • the region between the fixed and movable platens 9, 14 constitutes an effective clamping region 25.
  • the object to be clamped such as a two-piece mould (not shown), is located in the clamping region 25 and the hydraulic piston 21 drives the movable platen 14 towards the object and exerts sufficient pressure on the object so as to maintain it effectively and securely clamped.
  • any bending stresses acting on the clamping structure 3 merely results in a certain degree of bending of the latter without in any way affecting the basic spacing between the platens.
  • the bending stresses induced in the clamping structure 3 are transmitted via the pivotal coupling of the latter to the fixed platen 9 so as to ensure its even firmer clamping of the object against the movable platen 14.
  • the clamping assembly is provided with a fixed platen 41 which is formed integrally with a rigid, elongated rectangular base frame 42 constituting a positioning structure.
  • a movable platen 43 is rigidly coupled to a piston drive rod 44 of a hydraulic drive piston 45.
  • the drive piston 45 is held in a piston mounting bracket 46.
  • Both the movable platen 43 and the bracket 46 are slidably supported on the upper surfaces of elongated ribs 47, the undersurfaces of the movable platen 43 and the bracket 46, together with the upper surfaces of the ribs 47, constituting sliding contact bearings.
  • a pair of clamping arms 48 extends longitudinally within the rectangular base frame 42 and adjacent a pair of longitudinal sides thereof.
  • One adjacent pair of upturned end portions 48a of the clamping arms 48 are respectively and pivotally coupled to opposite sides of the mounting bracket 46 whilst an opposite pair of adjacent upturned ends 48b of the clamping arms 48 are pivotally coupled to the fixed platen 41.
  • the movable platen 43 and the hydraulic drive piston 45 form a unit which rests on the positioning structure (the movable platen 43 being longitudinally slidable with respect to the positioning structure.
  • the reaction on the fixed and movable platens 41 and 43 as a result of clamping pressure being exerted on the clamped object does not result in any distortion of the positioning structure but, if anything, results in a slight bending of the clamping arms 48. This does not, of course, affect the spacing between the platens 41 and 43 but merely results in the fixed platen 41 being more firmly pressed against the clamped object.
  • the clamping assembly is essentially similar to that described with reference to Figs. 3 and 4, with the sole exception that, whereas in the assembly shown in Figs. 3 and 4 the clamping arms 48 (i.e. the clamping structure) are located within the rectangular base frame 42 (i.e. the positioning structure), in the assembly shown in Fig. 5 of the drawings, the clamping arms 48' are located outside the base frame 42' and respectively adjacent the outside longitudinal sides thereof. In this way, the entire region between the platens and within the base frame 42' remains unencumbered by the clamping structure.
  • Fig. 6 of the drawings illustrates a clamping assembly of the kind illustrated in Fig. 5 of the drawings, namely one wherein clamping arms 48'' are located outside a base frame 42'', but in this case a movable platen 43' is coupled to a hydraulic drive system 49 via a toggle lever assembly 50.
  • the drive system 49 is used to activate the toggle assembly to displace the movable platen 43'.
  • the toggle assembly 50 serves as a positive stop and pressure holding device during injection. This type of assembly responds very quickly to opening and closing displacements of the movable platen 43'.
  • clamping assemblies in accordance with the invention are capable of operating with high clamping pressures without introducing any distortions in the clamping region. It will be readily seen that with such an assembly wherein the fixed and movable platens are not associated with tie bars, the clamping region is readily accessible for the ready introduction and removal of the mould and for the mechanical handling thereof.
  • the assembly includes a base frame 51 having an integrally formed fixed platen 52 and a movable platen 53.
  • the latter has integrally formed, longitudinally extending support limbs 54 between which are mounted sliding rollers 55 which slide in a longitudinally extending slot 56 formed in the base frame 51, the rollers 55 and slot 56 constituting together sliding contact bearings.
  • the region between the platens 52 and 53 constitutes a clamping region 57, in which is shown located a two-piece mould 58.
  • Formed integrally with the end of the base frame 51 closest the movable platen 53 is a support post 59 which has pivotally mounted thereon a hydraulic piston 60 whose drive rod 61 is pivotally coupled to the movable platen 53.
  • the sliding contact bearings constituted by the rollers 55 and the slot 56, are substantially located outside the clamping region 57 and, in consequence, when clamping pressure is applied to the movable platen 53 by the drive rod 61, the counteracting forces acting on the base frame 51 via the support post 59 leads to the bending distortion of that portion of the base frame 51 outside the clamping region 57 without affecting the clamping region itself.
